--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think we should warn about this if the second argument is a string literal,
not when optimizers propagate a pointer to a string literal to it, so do it in
the FEs, make sure it handles strncmp inline -D_FORTIFY_SOURCE=2 wrapper and
also handle strncasecmp as well.
